Unbending of sheet metal part, sheet metal detected automatically

For unbending, you can detect sheet metal automatically. This works if detected objects have the thickness significantly smaller than the other dimensions. Surface development (sheet metal unbending) uses the bending coefficients. These coefficients correct the unbent dimensions according to the sheet thickness.

In this example, the entire solid is detected at once. Then confirm the thickness and locate the unbent shape in 2D area.

For more information about surface development, see Surface Development.

Unbending, selection of the surface, creation of XY coordinates of the unbent surface

You can select each patch of the solid for unbending. After the selection, define the sheet thickness. In the following example, the file containing XY coordinates of unbent surface is created. Coordinates are listed for outline points in 2D, where leaders mark their locations.

Here, the selected surface is the outer surface of the full cylinder. The result is the same as for unbending pipe.
